A brief article detailing my initial efforts at the International Centre for Radio Astronomy Research to create simulations that follow the formation of galaxies across millions of lightyears of space.

Alan Duffy
My first SPH simulation paper on the "Impact of baryon physics on dark matter structures: a detailed simulation study of halo density profiles". It demonstrated that the physics of galaxy formation can (surprisingly) strongly affect the dark matter distribution. It won the "Best Paper by a UWA Early Career Researcher" award. Reference: Duffy, Schaye, Kay, Dalla Vecchia, Battye, Booth 2010 MNRAS 405 2161D

Alan Duffy
This was the main simulation paper for the OverWhelmingly Large Simulations (OWLS) effort that I was involved with during my PhD. This paper in particular focuses on the impact that different baryonic processes can have on the global star-formation rate, amongst many other effects. Reference: Schaye, Dalla Vecchia, Booth, Wiersma, Theuns, Haas, Bertone, Duffy, McCarthy, vd Voort 2010 MNRAS 402 1536-1560

Alan Duffy
A letter concerning the developments for (what will be) the World's largest single dish telescope, the Five-Hundred metre Aperture Spherical Telescope. Precocious and self-promoting but I had nearly finished my PhD and was feeling pretty opinionated!

Alan Duffy
My first N-body simulation paper (as well as Letter) on the topic of "Dark matter halo concentrations in the Wilkinson Microwave Anisotropy Probe year 5 cosmology" when I was based at Leiden Observatory. It demonstrated a fascinating inverse relation between the concentration (compactness) of a dark matter object and the mass of said object. Reference: Duffy, Schaye, Kay, Dalla Vecchia 2008 MNRAS 390L 64D

Alan Duffy
My first publication in a journal, on the subject of "Galaxy redshift surveys selected by neutral hydrogen using the Five-hundred metre Aperture Spherical Telescope". The telescope will be a fantastic survey instrument, capable of detecting millions to hundreds of millions of galaxies around us for billions of light years. Reference: Duffy, Battye, Davies, Moss, Wilkinson 2008 MNRAS 383 150D

My first scientific presentation at an international radio conference "From Planets to Dark Energy: the Modern Radio Universe" back in October 1-5 2007. Hosted at The University of Manchester, UK. Published online at SISSA, Proceedings of Science, p.91 Reference: Duffy, Battye, Davies, Moss, Wilkinson 2007 MRU ConfE 91D
